Massage Parlor

Build large weapons, break backs.

Weapon choices:
Spectral Scythe because it's unblockable.
Backbreaker can usually get pretty good armor in this deck.
Massive Greatsword in market is available if you need a weapon but can't draw one, or if you run into relic removal.
Siphoner Paladin can either make a weapon or buff your weapon by sacrificing another unit.

Ways to buff weapons:
Siphoner Paladin as mentioned already.
Jadehorn gets a bit more armor and a second attack.
The Nightmare Gates another way to sacrifice a unit to buff weapon.
Telut, The Iron Gate with his amazing surge synergy here.

Ways to protect weapons:
Telut, The Iron Gate surging also debuffs enemy units.
Rolant, Iron Tyrant generates nasty tokens every time an enemy unit dies.
Silverblade Intrusion is a very useful trick for protecting your key weapon protectors.

Units to sacrifice:
Basically everything besides Telut, The Iron Gate and Rolant, Iron Tyrant is fine to sacrifice most of the time. Bonus points if Oskar, Chief Tinker is activated.
